Pull remoteproc updates from Bjorn Andersson:
- Move requesting of IRQs in TI Keystone driver to probe time instead
of remoteproc start, to allow better handling of errors.
- Introduce support for more than 10 entries in the Qualcomm minidump
implementation.
- Add audio DSP remoteproc support for the Qualcomm Eliza platform. Add
modem remoteproc support for the Qualcomm MDM9607, MSM8917, MSM8937,
and MSM8940 platforms.
- Add list of Qualcomm QMI service ids to the QMI header file, in order
to avoid sprinkling them across the various drivers using them.
Migrate sysmon to use this constant.
- Fix several issues related to DeviceTree parsing and mailbox handling
in the Xilinx R5F remote processor driver.
- Fix incorrect error checks in reserved memory handling and polish the
code across i.MX and TI drivers.

Pull tracing latency update from Steven Rostedt:
- Add TIMERLAT_ALIGN osnoise option
Add a timer alignment option for timerlat that makes it work like the
cyclictest -A option. timelat creates threads to test the latency of
the kernel. The alignment option will have these threads trigger at
the alignment offsets from each other. Instead of having each thread
wake up at the exact same time, if the alignment is set to "20" each
thread will wake up at 20 microseconds from the previous one.
* tag 'trace-latency-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
tracing/osnoise: Add option to align tlat threads
Pull tracing updates from Steven Rostedt:
- Fix printf format warning for bprintf
sunrpc uses a trace_printk() that triggers a printf warning during
the compile. Move the __printf() attribute around for when debugging
is not enabled the warning will go away
- Remove redundant check for EVENT_FILE_FL_FREED in
event_filter_write()
The FREED flag is checked in the call to event_file_file() and then
checked again right afterward, which is unneeded
- Clean up event_file_file() and event_file_data() helpers
These helper functions played a different role in the past, but now
with eventfs, the READ_ONCE() isn't needed. Simplify the code a bit
and also add a warning to event_file_data() if the file or its data
is not present
- Remove updating file->private_data in tracing open
All access to the file private data is handled by the helper
functions, which do not use file->private_data. Stop updating it on
open
- Show ENUM names in function arguments via BTF in function tracing
When showing the function arguments when func-args option is set for
function tracing, if one of the arguments is found to be an enum,
show the name of the enum instead of its number
- Add new trace_call__##name() API for tracepoints
Tracepoints are enabled via static_branch() blocks, where when not
enabled, there's only a nop that is in the code where the execution
will just skip over it. When tracing is enabled, the nop is converted
to a direct jump to the tracepoint code. Sometimes more calculations
are required to be performed to update the parameters of the
tracepoint. In this case, trace_##name##_enabled() is called which is
a static_branch() that gets enabled only when the tracepoint is
enabled. This allows the extra calculations to also be skipped by the
nop:
if (trace_foo_enabled()) {
x = bar();
trace_foo(x);
}
Where the x=bar() is only performed when foo is enabled. The problem
with this approach is that there's now two static_branch() calls. One
for checking if the tracepoint is enabled, and then again to know if
the tracepoint should be called. The second one is redundant
Introduce trace_call__foo() that will call the foo() tracepoint
directly without doing a static_branch():
if (trace_foo_enabled()) {
x = bar();
trace_call__foo();
}
- Update various locations to use the new trace_call__##name() API
- Move snapshot code out of trace.c
Cleaning up trace.c to not be a "dump all", move the snapshot code
out of it and into a new trace_snapshot.c file
- Clean up some "%*.s" to "%*s"
- Allow boot kernel command line options to be called multiple times
Have options like:
ftrace_filter=foo ftrace_filter=bar ftrace_filter=zoo
Equal to:
ftrace_filter=foo,bar,zoo
- Fix ipi_raise event CPU field to be a CPU field
The ipi_raise target_cpus field is defined as a __bitmask(). There is
now a __cpumask() field definition. Update the field to use that
- Have hist_field_name() use a snprintf() and not a series of strcat()
It's safer to use snprintf() that a series of strcat()
- Fix tracepoint regfunc balancing
A tracepoint can define a "reg" and "unreg" function that gets called
before the tracepoint is enabled, and after it is disabled
respectively. But on error, after the "reg" func is called and the
tracepoint is not enabled, the "unreg" function is not called to tear
down what the "reg" function performed
- Fix output that shows what histograms are enabled
Event variables are displayed incorrectly in the histogram output
Instead of "sched.sched_wakeup.$var", it is showing
"$sched.sched_wakeup.var" where the '$' is in the incorrect location

Pull kvm updates from Paolo Bonzini:
"Arm:
- Add support for tracing in the standalone EL2 hypervisor code,
which should help both debugging and performance analysis. This
uses the new infrastructure for 'remote' trace buffers that can be
exposed by non-kernel entities such as firmware, and which came
through the tracing tree
- Add support for GICv5 Per Processor Interrupts (PPIs), as the
starting point for supporting the new GIC architecture in KVM
- Finally add support for pKVM protected guests, where pages are
unmapped from the host as they are faulted into the guest and can
be shared back from the guest using pKVM hypercalls. Protected
guests are created using a new machine type identifier. As the
elusive guestmem has not yet delivered on its promises, anonymous
memory is also supported
This is only a first step towards full isolation from the host; for
example, the CPU register state and DMA accesses are not yet
isolated. Because this does not really yet bring fully what it
promises, it is hidden behind CONFIG_ARM_PKVM_GUEST +
'kvm-arm.mode=protected', and also triggers TAINT_USER when a VM is
created. Caveat emptor
- Rework the dreaded user_mem_abort() function to make it more
maintainable, reducing the amount of state being exposed to the
various helpers and rendering a substantial amount of state
immutable
- Expand the Stage-2 page table dumper to support NV shadow page
tables on a per-VM basis
- Tidy up the pKVM PSCI proxy code to be slightly less hard to
follow
- Fix both SPE and TRBE in non-VHE configurations so that they do not
generate spurious, out of context table walks that ultimately lead
to very bad HW lockups
- A small set of patches fixing the Stage-2 MMU freeing in error
cases
- Tighten-up accepted SMC immediate value to be only #0 for host
SMCCC calls
- The usual cleanups and other selftest churn
LoongArch:
- Use CSR_CRMD_PLV for kvm_arch_vcpu_in_kernel()
- Add DMSINTC irqchip in kernel support
RISC-V:
- Fix steal time shared memory alignment checks
- Fix vector context allocation leak
- Fix array out-of-bounds in pmu_ctr_read() and pmu_fw_ctr_read_hi()
- Fix double-free of sdata in kvm_pmu_clear_snapshot_area()
- Fix integer overflow in kvm_pmu_validate_counter_mask()
- Fix shift-out-of-bounds in make_xfence_request()
- Fix lost write protection on huge pages during dirty logging
- Split huge pages during fault handling for dirty logging
- Skip CSR restore if VCPU is reloaded on the same core
- Implement kvm_arch_has_default_irqchip() for KVM selftests
- Factored-out ISA checks into separate sources
- Added hideleg to struct kvm_vcpu_config
- Factored-out VCPU config into separate sources
- Support configuration of per-VM HGATP mode from KVM user space
s390:
- Support for ESA (31-bit) guests inside nested hypervisors
- Remove restriction on memslot alignment, which is not needed
anymore with the new gmap code
- Fix LPSW/E to update the bear (which of course is the breaking
event address register)
x86:
- Shut up various UBSAN warnings on reading module parameter before
they were initialized
- Don't zero-allocate page tables that are used for splitting
hugepages in the TDP MMU, as KVM is guaranteed to set all SPTEs in
the page table and thus write all bytes
- As an optimization, bail early when trying to unsync 4KiB mappings
if the target gfn can just be mapped with a 2MiB hugepage
x86 generic:
- Copy single-chunk MMIO write values into struct kvm_vcpu (more
precisely struct kvm_mmio_fragment) to fix use-after-free stack
bugs where KVM would dereference stack pointer after an exit to
userspace
- Clean up and comment the emulated MMIO code to try to make it
easier to maintain (not necessarily "easy", but "easier")
- Move VMXON+VMXOFF and EFER.SVME toggling out of KVM (not *all* of
VMX and SVM enabling) as it is needed for trusted I/O
- Advertise support for AVX512 Bit Matrix Multiply (BMM) instructions
- Immediately fail the build if a required #define is missing in one
of KVM's headers that is included multiple times
- Reject SET_GUEST_DEBUG with -EBUSY if there's an already injected
exception, mostly to prevent syzkaller from abusing the uAPI to
trigger WARNs, but also because it can help prevent userspace from
unintentionally crashing the VM
- Exempt SMM from CPUID faulting on Intel, as per the spec
- Misc hardening and cleanup changes
x86 (AMD):
- Fix and optimize IRQ window inhibit handling for AVIC; make it
per-vCPU so that KVM doesn't prematurely re-enable AVIC if multiple
vCPUs have to-be-injected IRQs
- Clean up and optimize the OSVW handling, avoiding a bug in which
KVM would overwrite state when enabling virtualization on multiple
CPUs in parallel. This should not be a problem because OSVW should
usually be the same for all CPUs
- Drop a WARN in KVM_MEMORY_ENCRYPT_REG_REGION where KVM complains
about a "too large" size based purely on user input
- Clean up and harden the pinning code for KVM_MEMORY_ENCRYPT_REG_REGION
- Disallow synchronizing a VMSA of an already-launched/encrypted
vCPU, as doing so for an SNP guest will crash the host due to an
RMP violation page fault
- Overhaul KVM's APIs for detecting SEV+ guests so that VM-scoped
queries are required to hold kvm->lock, and enforce it by lockdep.
Fix various bugs where sev_guest() was not ensured to be stable for
the whole duration of a function or ioctl
- Convert a pile of kvm->lock SEV code to guard()
- Play nicer with userspace that does not enable
KVM_CAP_EXCEPTION_PAYLOAD, for which KVM needs to set CR2 and DR6
as a response to ioctls such as KVM_GET_VCPU_EVENTS (even if the
payload would end up in EXITINFO2 rather than CR2, for example).
Only set CR2 and DR6 when consumption of the payload is imminent,
but on the other hand force delivery of the payload in all paths
where userspace retrieves CR2 or DR6
- Use vcpu->arch.cr2 when updating vmcb12's CR2 on nested #VMEXIT
instead of vmcb02->save.cr2. The value is out of sync after a
save/restore or after a #PF is injected into L2
- Fix a class of nSVM bugs where some fields written by the CPU are
not synchronized from vmcb02 to cached vmcb12 after VMRUN, and so
are not up-to-date when saved by KVM_GET_NESTED_STATE
- Fix a class of bugs where the ordering between KVM_SET_NESTED_STATE
and KVM_SET_{S}REGS could cause vmcb02 to be incorrectly
initialized after save+restore
- Add a variety of missing nSVM consistency checks
- Fix several bugs where KVM failed to correctly update VMCB fields
on nested #VMEXIT
- Fix several bugs where KVM failed to correctly synthesize #UD or
#GP for SVM-related instructions
- Add support for save+restore of virtualized LBRs (on SVM)
- Refactor various helpers and macros to improve clarity and
(hopefully) make the code easier to maintain
- Aggressively sanitize fields when copying from vmcb12, to guard
against unintentionally allowing L1 to utilize yet-to-be-defined
features
- Fix several bugs where KVM botched rAX legality checks when
emulating SVM instructions. There are remaining issues in that KVM
doesn't handle size prefix overrides for 64-bit guests
- Fail emulation of VMRUN/VMLOAD/VMSAVE if mapping vmcb12 fails
instead of somewhat arbitrarily synthesizing #GP (i.e. don't double
down on AMD's architectural but sketchy behavior of generating #GP
for "unsupported" addresses)
- Cache all used vmcb12 fields to further harden against TOCTOU bugs
x86 (Intel):
- Drop obsolete branch hint prefixes from the VMX instruction macros
- Use ASM_INPUT_RM() in __vmcs_writel() to coerce clang into using a
register input when appropriate
- Code cleanups
guest_memfd:
- Don't mark guest_memfd folios as accessed, as guest_memfd doesn't
support reclaim, the memory is unevictable, and there is no storage

Pull SoC devicetree updates from Arnd Bergmann:
"A number of SoC platforms are adding modernized variants of their
already supported chips time, with a total of 12 new SoCs, and two
older SoC getting removed:
- Qualcomm Glymur is a compute SoC using 18 Oryon-2 CPU cores
- Qualcomm Mahua is a variant of Glymur with only 12 CPU cores, but
largely identical.
- Qualcomm Eliza is an embeded platform for mobile phone (SM7750) and
IOT (QC7790S/M) workloads
- Qualcomm IPQ5210 is a wireless networking SoC using Cortex-A53
cores
- Qualcomm apq8084 and ipq806x had only rudimentary support but no
actual products using them, so they are now gone.
- Axis ARTPEC-9 is a follow-up to the ARTPEC-8 embedded SoC, using
the Samsung SoC platform but now with Cortex-A55 cores
- ARM Zena is a virtual platform in FVP using Cortex-A720AE cores,
with additional versions planned to be merged in the future.
- ARM corstone-1000-a320 is a reference platform for IOT, using
low-end Cortex-A320 cores
- Microchip LAN9691 is an updated 64-bit variant of the arm32 lan966x
series of networking SoCs
- Microchip PIC64GX is an embedded RISC-V chip using SIFIVE U54 CPU
cores
- Rockchip RV1103B is the low-end 32-bit single-core vision processor
- Renesas RZ/G3L (r9a08g046) is an industrial embedded chip using
Cortex-A55 cores, similar to the G3E and G3S variants we already
supported.
- NXP S32N79 is an automotive SoC using Cortex-A78AE cores, a
significant upgrade from the older S32V and S32G series
These all come with at least one reference board or an initial product
using these, in total there are 67 newly added boards. The ones for
already supported SoCs are:
- Two more Aspeed BMC based boards
- Three older tablets based on 32-bit OMAP4 and Exynos5 SoCs
- One Set-top-box based on Allwinner H6
- 22 additional industrial/embedded boards using 64-bit NXP i.MX8M or
i.MX9 SoCs
- 20 Qualcomm SoC based machines across all possible markets:
workstation, gaming, laptop, phone, networking, reference, ...
- Three more Rockchips rk35xx based boards
- Four variants of the Toradex Verdin using TI AM62
Other notable bits are:
- A cleanup for the 32-bit Tegra paz00 board moved the last board
specific code on Tegra into equivalent dts syntax.
- There continues to be a significant number of fixes for static
checking of dtc syntax, but it feels like this is slowing down,
hopefully getting into a state where most known issues are
addressed
- Additional hardware support for many existing boards across SoC
families, notably Qualcomm, Broadcom, i.MX2, i.MX6, Rockchips,

A quite far-reaching cleanup to this code. I can't do better than to
quote Christoph:
"The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography
and not using the crypto API, with the generic implementations
sitting in include/asm-generic and the arch implementations
sitting in an asm/ header in theory. The latter doesn't work for
many cases, so architectures often build the code directly into
the core kernel, or create another module for the architecture
code.
Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric
Biggers has done for the CRC and crypto libraries later. After
that it changes to better calling conventions that allow for
smarter architecture implementations (although none is contained
here yet), and uses static_call to avoid indirection function call
overhead"

Add an option called TIMERLAT_ALIGN to osnoise/options, together with a
corresponding setting osnoise/timerlat_align_us.
This option sets the alignment of wakeup times between different
timerlat threads, similarly to cyclictest's -A/--aligned option. If
TIMERLAT_ALIGN is set, the first thread that reaches the first cycle
records its first wake-up time. Each following thread sets its first
wake-up time to a fixed offset from the recorded time, and increments
it by the same offset.
Example:
osnoise/timerlat_period is set to 1000, osnoise/timerlat_align_us is
set to 20. There are four threads, on CPUs 1 to 4.
- CPU 4 enters first cycle first. The current time is 20000us, so
the wake-up of the first cycle is set to 21000us. This time is recorded.
- CPU 2 enter first cycle next. It reads the recorded time, increments
it to 21020us, and uses this value as its own wake-up time for the first
cycle.
- CPU 3 enters first cycle next. It reads the recorded time, increments
it to 21040 us, and uses the value as its own wake-up time.
- CPU 1 proceeds analogically.
In each next cycle, the wake-up time (called "absolute period" in
timerlat code) is incremented by the (relative) period of 1000us. Thus,
the wake-ups in the following cycles (provided the times are reached and
not in the past) will be as follows:
CPU 1 CPU 2 CPU 3 CPU 4
21080us 21020us 21040us 21000us
22080us 22020us 22040us 22000us
... ... ... ...
Even if any cycle is skipped due to e.g. the first cycle calculation
happening later, the alignment stays in place.

A pattern property matching essentially anything doesn't work if there
are implicit properties such as 'phandle' which can occur on any node.
One such example popped up recently:
arch/arm64/boot/dts/qcom/sm8650-hdk.dtb: thermal-zones: gpuss0-thermal:trips:phandle: 531 is not of type 'object'
from schema $id: http://devicetree.org/schemas/thermal/thermal-zones.yaml
Instead of a pattern property, use an "additionalProperties" schema
instead which is the fallback in case of no matching property.

The function testdrv_probe() retrieves the device_node from the PCI
device, applies an overlay, and then immediately calls of_node_put(dn).
This releases the reference held by the PCI core, potentially freeing
the node if the reference count drops to zero. Later, the same freed
pointer 'dn' is passed to of_platform_default_populate(), leading to a
use-after-free.
The reference to pdev->dev.of_node is owned by the device model and
should not be released by the driver. Remove the erroneous of_node_put()
to prevent premature freeing.

The variable 'parent' is assigned the value of 'nchangeset' earlier in the
function, meaning both point to the same struct device_node. The call to
of_node_put(nchangeset) can decrement the reference count to zero and
free the node if there are no other holders. After that, the code still
uses 'parent' to check for the presence of a property and to read a
string property, leading to a use-after-free.
Fix this by moving the of_node_put() call after the last access to
'parent', avoiding the UAF.
